Operator Space Transport and the Emergence of Boundary Time Crystals
Dominik Nemeth, Ahsan Nazir, Robert-Jan Slager +1
Boundary time crystals (BTCs) are prominent examples of continuous time crystals in collective spin systems governed by Lindbladian evolution. To date, their analysis has mostly re…

Topological Boundary Time Crystal Oscillations
Dominik Nemeth, Ahsan Nazir, Alessandro Principi +1
Boundary time crystals (BTCs) break time-translation symmetry and exhibit long-lived, robust oscillations insensitive to initial conditions. We show that collective spin BTCs can a…

Analytical solution of boundary time crystals via the superspin basis
Dominik Nemeth, Alessandro Principi, Ahsan Nazir
Boundary time crystals (BTCs) in dissipative collective spin systems have been extensively studied using numerical, mean-field, and perturbative approaches. However, an explicit Li…
